Mandy Roper, Debbie Hayashi, and Annie Johnson act as co-principals.  Together they serve as the leadership team for H.E.A.R.T.


We are so pleased to welcome back each of our returning instructors and invite our new teachers to join us. All of our instructors are passionate about the subjects they teach, masters of getting children excited about learning and faithful followers of our Lord.

Laura D'Argo (Art/Advance Art/3D Art): “To my mind, a picture should be something pleasant, cheerful and pretty – yes pretty! There are plenty of unpleasant things in life as it is without creating still more of them.”  This is a quote by Pierre Auguste Renoir, a French Impressionist, circa 1880’s. Laura heard this quote in college, Columbia College, Chicago, and it simply summed up her philosophy of art. Be it fine art or illustration, joy can be communicated and then settles in the soul of a person. Joy, illustrated by an orchid growing from a crack in a rock, tells a story of hope.  Laura is a gifted artist and a professional illustrator who loves bringing out the artist in all of her students. 

Mike Estes (Basic Business): Mike and his wife homeschool their twins, Mitch and Norah.  Mike has worked in a variety of business fields and even owned his own company.  Mike has enjoyed teaching unit studies at H.E.A.R.T. in addition to running our "Pizza Day".  He is excited to be on staff as our business teacher!

Delilah Fritzler (Forensics/Cooking and Baking/Gardening/Sewing): Delilah Fritzler is a mother of three and a former middle school teacher. She graduated from Southern Illinois University in 2005 with K-9th certification and endorsements in Language Arts and Social Sciences. She and her husband Brett are thrilled to be homeschooling their children and are so grateful for God's clear leading in this area. Delilah believes teaching is more than just a profession for the classroom; it is a responsibility given to each of us in our area of gifting to live out God's simple plan for discipleship.

Deb Hayashi (H.E.A.R.T. Leadership Team/Physical Education/Bible Study): Debbi Hayashi received her Masters in Arts Degree from Loyola University, Chicago.  God has blessed Debbi with her husband Brad and four wonderful children.  Debbi's second career in life has been an adventure of being a CEO, CFO, Executive Chef, Head Maid, Lead Landscaper, and Child Behavior Researcher of Hayashi, Inc.  In addition in 2012, Debbi felt called to start homeschooling her children.  Debbi accepted Christ as her Savior in March, 1997 and is continually trying to strive to live a Christ-centered life.  

Annie Johnson (H.E.A.R.T. Leadership Team/Drama/Performance/Sign Language/Critical Thinking): Annie and her husband Wes have two wonderfully wild little boys.  Annie graduated from Trinity International University with a degree in English/Communications in 2007.  Since then, Annie has worked as a Campus Life Director with Youth for Christ, been a teacher in a private school, enjoyed being a freelance photographer, and most recently has taken on the fabulous and challenging role as a stay at home mom.   Annie has loved teaching in different capacities at H.E.A.R.T since 2012. 

Leona Kim (Project Club):  Leona has been married to her husband, Jin, for 19 years. They have three homeschooled daughters, Hannah, Sarah, and Jayne. Having always loved working with her hands and crafting, it has been a joy for her and her family to own and operate a crafting company in recent years. Leona considers it an honor to encourage children to view crafts from a Biblical perspective. She believes that crafting builds skills in children that can translate to many other areas of life and that can be used for God's glory and to minister to others for their lifetime. 

Mandy Roper (H.E.A.R.T. Leadership Team/Spanish/Music/Performance): Mandy is a homeschool mom to Nathan, Natalie Jo, and Nadia.  She is a certified teacher (music, early childhood, elementary, math and bilingual/ESL) who finds great joy in teaching young children. Mandy enjoys planning lessons that not only teach a necessary concept, but also allow them to have fun. Music has always been a part of her life. It motivates her, provides enjoyment, and allows her to relax. Mandy’s desire is for her students to be able to enjoy all types of music and to feel confident in using it to worship the Lord.
